This is great! I've read about recent remarks about sightings, but I didn't know an announcement is forthcoming.
I recall reading a book about some related stuff, Top Secret/Majic: Operation Majestic-12 and the United States Government's UFO Cover-up. I have a poor memory of it, but I think I recall that while there is certainly not a lot of definitive information to declare with certainty that there has indeed been a cover up per se, there really is a great lack of material to draw from. And of course whatever can be obtained would often have been heavily redacted, etc.

Still, I think probably more of a contributing factor might be the fact that so few records are actually archived as a standard! According to the National Archives, only 1-3% of materials that get produced get archived! That doesn't make it easy to piece together historical meetings and memos, and the effects of them! Something or other related to the sorts of things like PROJECT BLUE BOOK was discovered in some kind of clean out of an army barracks or something in 2013. I don't remember the details, but records have been scoured by internal and external sources, and there's really not a satisfactory breadth of material available. That's the gist I get.

I agree with Snyder that we'll likely not get much more from the authorities than we've heard in the past. From my perspective, though, it's not necessarily because somebody knows something that is being hidden. Rather, it's that we (even the authorities) simply don't know. This perspective is also disclosed by Snyder with an example of a colony of sea creatures that had at one time been thought to be extinct currently living off the coast of Madigascar; it's true that there is so much we really don't understand. Certainly, this extends from the sea to the sky (and right down to the very particles that make up our whole universe!).

In terms of significant disclosures, I do hope something interesting will be revealed in the name of science! But, I think it's more likely that sightings are more commonplace than we generally realize. According to the International Civil Aviation Organization, we're flying about twice as many miles overall than we did ten years ago commercially. Is that true of military flights as well?

In addition, while hobbyists who track flights and flight anomalies have been around for a long time, does the more widespread use of social media bring their findings to bear more quickly and with more impact these days than it used to?

Maybe what's been happening in our skies all along is simply more out in the open these days. Still, an upcoming announcement is something to anticipate with excitement! Thank you for posting this.
